Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety device for a vehicle entrance/exit door of a mechanical parking system.

Conventionally, the safety device for the entrance/exit door of a mechanical parking device is such that, for example, if a foreign object gets caught in the door and the overcurrent relay is activated and the entrance/exit door cannot be closed safely, the mechanical parking device is activated for safety. Sufficient safety measures have been put in place to prevent one door from being closed, such as making it impossible to drive.

However, it is natural for entrance/exit doors to fail to open completely, but in this case there is a strong recognition that this is a safety-related failure that prevents the mechanical parking system from operating, and no countermeasures have been taken in the past. .

For this reason, once the door begins to open, it will open all the way. This may give parking device managers and users a preconceived notion that the parking device will not be able to enter or exit the parking device even if the entrance door is left ajar due to the same cause, such as a clog. Because of this, there have been cases where the vehicle body has hit the entrance/exit door, especially when leaving the garage by going backwards.

In view of the above points, it is an object of the present invention to provide a safety device that can prevent accidents caused by half-opening of an entrance/exit door.

An embodiment of the present invention will be described below with reference to the drawings.

In Section 1 and Figure 2, E+ and E- are power supply H line, L
S is a detection device consisting of a micro switch whose contact LSa opens when the entrance/exit door 10 of the parking device is completely opened; P) 11 and P) 12 are floodlight devices PI (1-A,
P) 12-A and light receiving device PHI-B.

In the adjacent photoelectric device consisting of PH2-8, when the light beam of the light projection bag FPHIA is heated by a person or a car, the contact point P Or if it is blocked by a car, the contact PH
2a is closed. SL is an operation switch for opening the entrance/exit door 10, and RYLS is a normally open contact RY when energized.
A door open confirmation relay that closes LSa and opens contact RYLSa when deenergized; a door open command relay that operates an entrance/exit door drive device (not shown) to open the entrance/exit door 10 when RYI is energized; RYla and RYlc are normally open contacts, RY2 is an abnormality detection relay that determines that some kind of failure has occurred in opening the door when energized, RY2a and R
Y2c is the normally open contact, RY3 is the east detection relay that determines that it is a car when energized, RY3b is the normally closed contact, RYBSI, RYBS2 are the light tail relays,
RYBSla, RYBSlc and RYBS2a.

RYBS2c are photoelectric relays RYBSI and R, respectively.
YBS2 normally open contact, RY4 and RY5 are photoelectric device operation memory relays, RY4a, RY4c and RY5a
, RY5c, and RY5d are the normally open contacts of the photoelectric device operation memory relays RY4 and RY5, respectively, RY6 is the detection relay that detects the entrance of a person, and RY6a is its normally open contact.
RY7 is a detection relay that detects the presence of a person, RY7b is its normally closed contact, TRYI, and RY2 is the activation delay relay 1, TRYla.

TRY2a are actuation delay relays TRYI and T, respectively.
RY2 is a time-limited operation normally open contact, TRY3 is a recovery delay relay, TRY3a is its time-limited return normally open contact, and 20 is a time-limited normally open contact that, when energized, visually or audibly warns the user that the doorway s10 is not fully opened. The prompt r display announcement device, BZ, is a buzzer.

The operation of the apparatus of the present invention will be explained below.

First, in order to enter or exit the garage, the empty cage or the exit cage is called to the parking device entry/exit 1 position by a well-known method, and then when the switch S1 that opens the entrance/exit door 10 is pressed, the door opening command relay RY1 closes the circuit. E+-SL
-RYI -E-, closed circuit 'E+-
RYla -RYLSa (door open confirmation relay RYLSa is energized) -RYI -E- is self-held and operates the door drive device to open the entrance/exit door 10, and the activation delay relay T is activated by closing the contact RYlc.
Apply voltage to RYI. Therefore, if the entrance/exit door 10 is not opened even after the predetermined time period for which the operation linkage relay TRYI operates, that is, the time required for normal door opening,
Since the contact LSa of the detection device LS does not open and the door open confirmation relay RYLS remains deenergized, a closed circuit 'E+
-TRYla -RYLSc energized, contact RY2a
Voltage is applied to the display announcement device by the closed circuit of
The fact that the entrance/exit door 10 is not fully opened is visually or aurally appealed to alert the user.

Therefore, since users and managers notice that the entrance/exit door is malfunctioning, they should, in principle, temporarily prohibit entry/exit operations and immediately begin repairing the malfunction.

However, there is a big downside to interrupting business activities midway through, even if it is due to a malfunction, so if you have no choice but to continue operating the parking system with a malfunction, you may manually close the entrance/exit door so that cars can enter and exit without hindering the operation of the parking system. It is also conceivable to open the door and continue the warehousing and unloading operations.

Incidentally, even if the display/announcement device 20 is activated, the manager and the user may not notice the malfunction of the entrance/exit door and the user may enter the tower to exit the tower. P)] A person plays with the ray of 1 and the contact point PH
1a is closed, the photoelectric relay RYBS1 is energized, the closed circuit 1E+-device operation memory relay RY4 is energized, and the contact RY
It is self-retained by the closed circuit 4a. Next, when the user goes further inside, the light beam of the photoelectric device PH2 is used to close the contact PH2a and energize the photoelectric relay RYBS2.
Closed circuit' E + -RY3b -RY7b -RYB
S2c-RY5 E-J causes the photoelectric device operation memory relay RY5 to self-hold by closing the energizing contact RY5a. At this time, of course, the light beam of the light 1 device P)+1 is incident on the light receiving device PHI-B, so the photoelectric relay R
YBSI is deenergized and photoelectric device operation record tQ l)
RY5 (7) Energized closed circuit' E+ -R
Y3b-RY7b-RY4c RYBSI RY5c
RY6 Activates detection relay RY6 through E-J, detects that a person is inside the tower, and closes the circuit 'E+-
RY3b -RY7b -RY2c -RY6a -B
A buzzer BZ is sounded through Z - E - J to further alert the users. When the user notices the sound of this buzzer and blocks the light beam in the order of photoelectric devices PH2 and PH1,
Closed circuit' E 10 -RY3b-RY7b-RY5d-
The detection relay RY7 is energized by RYBS2b-RYBS1dRY7E-a, and the relays RY4 to RY7 are deenergized by opening the contact RY7b, and the buzzer BZ is stopped.

Naturally, the sound of this buzzer will alert the administrator to the abnormality and allow them to take appropriate further action.

The vehicle inspection quantity relay RY3 is energized when the light beams of the photoelectric devices PHI and PH2 are both blocked for a predetermined time period during which the operation delay relay TRY2 operates, and it is activated to indicate that the vehicle is entering or exiting the garage. Although it is a relay that detects the problem, it is usually too late to notify that the entrance/exit door 10 is out of order while a car is entering or exiting the garage, so it is better to issue a warning when the user enters the parking lot before the most dangerous exit operation. is considered to be effective. Therefore, contact RY3b of vehicle inspection amount relay RY3
is inserted into one source line, and the buzzer circuit is configured to operate only when a person enters or exits, and the self-holding circuit of the vehicle inspection quantity relay RY3 includes a time-limited return contact T of the recovery delay relay TRY3.
RY3a f! : The structure is such that the self-holding is released by inserting the contact TRY3a and opening the contact TRY3a.

As described above, according to the present invention, if the entrance/exit door cannot be opened completely, the user or the manager is immediately notified of this fact. During operation, the user and the manager are further alerted and ventilated before starting the actual exit operation, so it is possible to prevent an accident such as a car hitting an entrance door.
